Kuumbwa kwethrombus kwakabatana nekukuvara kwevascular endothelial, hypercoagulability yeropa, uye kuderera kwekuyerera kweropa.Saka, vanhu vane izvi zvitatu zvinokonzera njodzi vanowanzoita thrombus.

1. Vanhu vane vascular endothelial kukuvadzwa, zvakadai seavo vakave nevascular puncture, venous catheterization, nezvimwewo, nekuda kwekukuvadzwa kwevascular endothelium, iyo collagen fibers yakazaruka pasi pe endothelium inogona kushandura maplatelet uye coagulation zvinhu, izvo zvinogona kutanga endogenous coagulation.Iyo system inokonzera thrombosis.

2. Vanhu vane ropa riri mu hypercoagulable state, vakadai sevarwere vane mapundu akaipa, systemic lupus erythematosus, kukuvadzwa kwakanyanya kana kuvhiyiwa kukuru, vane zvinhu zvakawanda zvekuvhara ropa muropa ravo uye vanogona kugwanda kudarika ropa remazuva ose, saka vanowanzoitika. kuita thrombosis.Mumwe muenzaniso ndewevanhu vanotora mishonga yekudzivirira kubata pamuviri, estrogen, progesterone nemamwe madhiragi kwenguva yakareba, ropa ravo coagulation basa richakanganiswawo, uye zviri nyore kuumba ropa.

3. Vanhu vane ropa rinodzikira, vakadai sevaya vakagara vakanyarara kwenguva yakareba vachitamba mahjong, kuona TV, kudzidza, kutora kirasi yehupfumi, kana kugara pamubhedha kwenguva yakareba, kushaikwa kwekuita zvemuviri kunogona kukonzera kuyerera kweropa kunonokesa kana kutombodzikama Kuumbwa kwemavortices kunoparadza yakajairika kuyerera kweropa mamiriro, izvo zvichawedzera mukana we maplatelet, endothelial masero uye coagulation zvinhu kuonana, uye zviri nyore kugadzira thrombus.
